Dynojet Power Vision 4 `21-UP

Ordered this Dynojet for mine Dyna fxdb 2007 bike, to connect this on the bike ecm, you need to order J1850 connector from Dyno jet, and then you can to connect . All work great

Install of tune was so easy. Load app on phone and plug into the bike. Very easy and user friendly

I rode 18000+ km on a stock 23 Softail 107 and am very aware of how it performs. Added slipon mufflers without any tuning and noticed a slight improvement in performance. Now have 20000km. Decided to do a full stage 1 by adding a high flow air cleaner and this frustrating PV4 device. Air cleaner install was simple and easy. First time booting up the PV4 all I got was error messages. Some time later after rebooting and resetting Bluetooth etc I finally got an error free connection. Flash the specific map and go for an 80km ride. Seat of the pants dyno tells me 2000 - 3000 rpm feels flat and lifeless now. This is the rev range I spend 99% of riding time. It was instantly responsive with plenty of giddy up on the stock tune. Feels a bit gutless now. The original grunty torque curve I loved has gone. Great, spend around $200 AU on an air cleaner kit, and nearly $800 AU for this dynojet paperweight that has made my bike run worse than stock. $50 worth of jets/needles, and an hour to install was all it took to do stage one carb tuning on my previous Harleys, always with positive outcomes. $800 (16 times the price) and a couple of hours frustration with this dynojet thing has resulted in a bike that runs worse, and instead of nice burbling when decelerating I now get random pops and bangs. Just got back from another 80km ride. The current tune has also created a dangerous stumble when moving off from stationary, twice causing me to nearly drop the bike. Right now I need to go back to stock tune and reinstall the stock air box and filter to get my original Better performance back, at least until I hopefully hear back from dynojet. Not holding my breath though. I do not recommend. Zero stars. p.s. I would not buy from this Amazon vendor again due to the slow dispatch and weird tracking.

great product works very well and works great
